- Tiny spectrometer offers precision laser calibration
05-10-2007 · EurekAlert!
A tiny device for calibrating or stabilizing precision lasers has been designed and demonstrated at NIST, and could replace table-top-sized instruments used for laser calibration in atomic physics research, could better stabilize optical telecommunications channels, and perhaps could replace and improve on the precision of instrumentation used to measure length, chemicals or atmospheric gases.

- Class of medications may offer alternative option for treating type 2 diabetes
07-10-2007 · EurekAlert!
A review of previous studies indicates that use of a class of medications known as "incretin-based therapy," which act via certain pathways that affect glucose metabolism may provide modest effectiveness and favorable weight change outcomes for the treatment of type 2 diabetes and may represent an alternative to other hypoglycemic therapies, according to an article in the July 11 issue of JAMA.

- New clinical guideline for low-back pain
10-02-2007 · EurekAlert!
A summary of evidence on the diagnosis, treatment of low-back prompts the American Pain Society and the American College of Physicians to issue a new treatment guideline. The guideline is based on research conducted at the Oregon Evidence-Based Practice Center, Oregon Health & Science University. Among the recommendations: clinicians should rely less on X-rays and expensive diagnostic imaging and reports and more on therapies supported by the evidence, including some medications and some alternative therapies.

- New sensor detects gaseous chemical weapon surrogates in 45 seconds
03-19-2007 · EurekAlert!
Using lasers and tuning forks, Pacific Northwest National Laboratory scientists have developed a chemical weapon agent sensing technique that promises to meet or exceed current and emerging defense and homeland security chemical detection requirements. The technique, called Quartz Laser Photo-Acoustic Sensing, or "QPAS," is now ready for prototyping and field testing. PNNL has demonstrated QPAS's ability to detect gaseous nerve agent surrogates. The instrument is based on Laser Photo-Acoustic Sensing and infrared Quantum Cascade Lasers.
